LDA (Lane Departure
Aler t with steering
control)
*
When driving on highways
and freeways with white
(yellow) lane lines, this
function alerts the driver
when the vehicle might
depart from its lane or
course
* and provides assis-
tance by operating the
steering wheel to keep the
vehicle in its lane or
course
*.
The LDA system recog-
nizes white (yellow) lane
lines or a course
* using the
front camera. Additionally, it
detects preceding vehicles
using the front camera and
radar.
*: Boundary between asphalt and the side of the road, such as
grass, soil, or a curb

■Before using LDA system
●Do not rely solely upon the LDA
system. The LDA system does
not automatically drive the vehi-
cle or reduce the amount of
attention that must be paid to
the area in front of the vehicle.
The driver must always assume
full responsibility for driving
safely by paying careful atten-
tion to the surrounding condi-
tions and operating the steering
wheel to correct the path of the
vehicle. Also, the driver must
take adequate breaks when
fatigued, such as from driving
for a long period of time.
●Failure to perform appropriate
driving operations and pay care-
ful attention may lead to an
accident, resulting in death or
serious injury.
●When not using the LDA sys-
tem, use the LDA switch to turn
the system off.
■Situations unsuitable for LDA
system
In the following situations, use the
LDA switch to turn the system off.
Failure to do so may lead to an
accident, resulting in death or
serious injury.
●Vehicle is driven on a road sur-
face which is slippery due to
rainy weather, fallen snow,
freezing, etc.
●Vehicle is driven on a snow-cov-
ered road.
●White (yellow) lin es are difficult
to see due to rain, snow, fog,
dust, etc.
●A spare tire, tire chains, etc. are

excessively worn, or when the
tire inflation p ressure is low.
●When tires of a size other than
specified are installed.
●Vehicle is driven in traffic lanes
other than that highways and
freeways.
●During emergency towing.
■Preventing LDA system mal-
functions and operations per-
formed by mistake
●Do not modify the headlights or
place stickers, etc. on the sur-
face of the lights.
●Do not modify the suspension
etc. If the suspension etc. needs
to be replaced, contact your
Toyota dealer.
●Do not install or place anything
on the hood or grille. Also, do
not install a gr ille guard (bull
bars, kangaroo bar, etc.).
●If your windshield needs
repairs, contact your Toyota
dealer.
■Conditions in which functions
may not operate properly
In the following situations, the
functions may not operate prop-
erly and the vehicle may depart
from its lane. Drive safely by
always paying careful attention to
your surroundings and operate
the steering whee l to correct the
path of the vehicle without relying
solely on the functions.
●Vehicle is being driven around a
sharp curve.

alert the driver.
When the warning buzzer sounds,
check the area around your vehicle
and carefully operate the steering
wheel to move the vehicle back to
the center of the lane.

lane is high, the lane departure
alert will operate even if the turn
signals are operating.

■Hands off steering wheel warn-
ing
In the following situations, a warning
message urging the driver to hold
the steering wheel and the symbol
shown in the illustration are dis-
played on the multi-information dis-
play to warn the driver. The warning
stops when the sys tem determines
that the driver holds the steering
wheel. Always keep your hands on
the steering wheel when using this
system, regardless of warnings.
●When the system determines that
the driver is driving without hold-
ing the steering wheel while the
system is operating
If the driver continues to keep their
hands off of the steering wheel, the
buzzer sounds, the driver is warned
and the function is temporarily can-
celed. This warning also operates in
the same way when the driver con-
tinuously operates the steering
wheel only a small amount.
●When the system determines that
the vehicle may not turn and
instead depart from its lane while
driving around a curve
Depending on the vehicle condition
and road conditions, the warning
may not operate. Also, if the system
determines that the vehicle is driv- ing around a curve, warnings will
occur earlier than during
straight-lane driving.
●When the system determines that
the driver is driving without hold-
ing the steering wheel while the
steering wheel assi
st of the steer-
ing assist function is operating.
If the driver continues to keep their
hands off of the steering wheel and
the steering wheel assist is operat-
ing, the buzzer sounds and the
driver is warned. Each time the
buzzer sounds, the continuing time
of the buzzer becomes longer.
■Vehicle sway warning function
When the system determines that
the vehicle is swaying while the
vehicle sway warning function is
operating, a buzzer sounds and a
warning message urging the driver
to rest and the sym bol shown in the
illustration are simultaneously dis-
played on the multi-information dis-
play.
Depending on the vehicle and road
conditions, the warning may not
operate.
■Warning message
If the following warning message is
displayed on the multi-information
display and the LDA indicator illumi-
nates in orange, follow the appropri-
ate troubleshooting procedure. Also,
if a different warning message is
displayed, follow the instructions
displayed on the screen.

due to a malfuncti on in a sensor
other than the front camera. Turn
the LDA system off, wait for a little
while, and then turn the LDA system
back on.
●“LDA Unavailable at Current
Speed”
The function cannot be used as the
vehicle speed exceeds the LDA
operation range. Drive slower.
●“LDA Unavailable Below Approx.
32MPH”
The LDA system cannot be used as
the vehicle spee d is less than
approximately 32 mph (50 km/h).

■Before using dynamic radar
cruise control with full-speed

●Driving safely is the sole
responsibility of the driver. Do
not rely solely o n the system,
and drive safely by always pay-
ing careful attention to your sur-
roundings.
●The dynamic radar cruise con-
trol with full-speed range pro-
vides driving assistance to
reduce the driver’s burden.
However, there are limitations to
the assistance provided.
Read the following conditions
carefully. Do not overly rely on this
system and always drive carefully.
• When the sensor may not be correctly detect ing the vehicle
ahead:
P.238
• Conditions under which the vehicle-to-vehicle distance con-
trol mode may not function cor-
rectly:
P. 2 3 9
●Set the speed appropriately
depending on the speed limit,
traffic flow, road conditions,
weather conditions, etc. The
driver is responsible for check-
ing the set speed.
●Even when the system is func-
tioning normally, the condition of
the preceding vehicle as
detected by the system may dif-
fer from the condition observed
by the driver. Therefore, the
driver must always remain alert,
assess the danger of each situ-
ation and drive safely. Relying
solely on this system or assum-
ing the system ensures safety
while driving can lead to an
accident, result ing in death or
serious injury.
●Switch the dynamic radar cruise
control with full-speed range
setting to off, using the cruise
control main switch when not in
use.
■Cautions regarding the driv-
ing assist systems
Observe the following precau-
tions, as there ar e limitations to
the assistance provided by the
system. Failure to do so may
cause an accident resulting in
death or serious injury.
